Remote File Synchronization

Rsync (synchronize) is a remote data synchronization tool that allows you to quickly synchronize files between multiple hosts by LAN. You can also use rsync to synchronize different directories on your local hard disk. Rsync is a tool to replace RCP, and Rsync uses the so-called rsync algorithm for data synchronization, which transmits only two different parts of the file, rather than sending it all at a time, so it's very fast. You can refer to how to Rsync works A ...

Remote invocation is the communication mechanism between system and process, and is the core technology of distributed system development. Remote invocation technology can form a group of computer systems into a network system, the external provision of the overall service, then this group of computer systems constitute a larger, more performance of the computer system. A general statement on the architecture design of the remote invocation service first, we need to understand the following questions: Why is a remote invocation service required in an application software service? What is the problem with the remote Invoke service that solves the software design? I have written an article on the design of distributed Web site architecture, ...

1. The introduction of the Hadoop Distributed File System (HDFS) is a distributed file system designed to be used on common hardware devices. It has many similarities to existing distributed file systems, but it is quite different from these file systems. HDFS is highly fault-tolerant and is designed to be deployed on inexpensive hardware. HDFS provides high throughput for application data and applies to large dataset applications. HDFs opens up some POSIX-required interfaces that allow streaming access to file system data. HDFS was originally for AP ...

Original: http://hadoop.apache.org/core/docs/current/hdfs_design.html Introduction Hadoop Distributed File System (HDFS) is designed to be suitable for running in general hardware (commodity hardware) on the Distributed File system. It has a lot in common with existing Distributed file systems. At the same time, it is obvious that it differs from other distributed file systems. HDFs is a highly fault tolerant system suitable for deployment in cheap ...

The Rational Team Concert (RTC) is one of the most popular code management tools, but for source code synchronization on multiple stream, most http://www.aliyun.com/zixun/aggregation/7155. HTML > Developers are repeatedly submitting code on each stream and manually ensuring synchronization, which increases the cost of our usual development. This article will mainly introduce an effective method to achieve in the R ...

With the popularity and popularity of social internet and mobile devices, information sharing is everywhere. Personal file sharing using a network disk is more popular, fast, simple. Within the enterprise, employees use more and more mobile terminals. Employees need to share documents among different teams, between different devices, and the need for file sharing drives corporate online file sharing. According to the report of Enterprise Strategy Group (ESG), 28% of companies have used online file sharing, while 61% of companies are considering options. Storage technology with each passing day, in ...

Cloud computing has been hailed as the beginning of the fourth information revolution, with its full use of the Internet's penetration and seamless integration with mobile interconnecting devices, providing users with almost omnipotent super services. However, the data stored in the cloud on the one hand create unlimited value, on the other hand, is becoming a super hacker, network illegal organization, APT attack "target". 　　Over the past few years, the major public cloud manufacturers frequent leaks of the incident so that users are quite worried, the emergence of trust crisis so many enterprises have turned, choose to build private cloud storage platform. To build a private cloud that is both perfect and practical, businesses must ...

As a new computing model, cloud computing is still in its early stage of development. Many different sizes and types of providers provide their own cloud-based application services. This paper introduces three typical cloud computing implementations, such as Amazon, Google and IBM, to analyze the specific technology behind "cloud computing", to analyze the current cloud computing platform construction method and the application construction way. Chen Zheng People's Republic of Tsinghua University 1:google cloud computing platform and application Google's cloud computing technology is actually for go ...

Chen Jingxi: Hello, I am the world's Super Cloud product manager, "Super Warehouse-help build private storage Cloud", cloud everybody knows, cloud computing is very hot, Cang everybody first thought is what? Warehouses, and granaries, and grain. There are rice, put noodles. What kind of stuff is in the warehouse? Not now. I'm going to cook dinner tonight, I'll take the grain out of the warehouse, but I have a lot of reserves. The time to put in the warehouse, including goods, food, including any kind of reserve material is defined by the warehouse. The Super Warehouse we are going to introduce to you today is also based on this ...
